    Elimination of delayed-onset muscle soreness by pre-resistance cardioacceleration
    before each set.

    We compared delayed-onset muscle soreness (DOMS) induced by anaerobic resistance
    exercises with and without aerobic cardioacceleration before each set, under the
    rationale that elevated heart rate (HR) may increase blood perfusion in muscles
    to limit eccentric contraction damage and/or speed muscle recovery. In two
    identical experiments (20 men, 28 women), well-conditioned athletes paired by
    similar physical condition were assigned randomly to experimental or control
    groups. HR (independent variable) was recorded with HR monitors. DOMS (dependent
    variable) was self-reported using Borg's Rating of Perceived Pain scale. After
    identical pre-training strength testing, mean DOMS in the experimental and
    control groups was indistinguishable (P > or = 0.19) for musculature employed in
    eight resistance exercises in both genders, validating the dependent variable.
    Subjects then trained three times per week for 9 (men) to 11 (women) weeks in a
    progressive, whole-body, concurrent training protocol. Before each set of
    resistance exercises, experimental subjects cardioaccelerated briefly (mean HR
    during resistance training, 63.7% HR reserve), whereas control subjects rested
    briefly (mean HR, 33.5% HR reserve). Mean DOMS among all muscle groups and
    workouts was discernibly less in experimental than control groups in men (P =
    0.0000019) and women (P = 0.0007); less for each muscle group used in nine
    resistance exercises in both genders, discernible (P < 0.025) in 15 of 18
    comparisons; and less in every workout, discernible (P < 0.05) in 32% (men) and
    55% (women) of workouts. Most effect sizes were moderate. In both genders, mean
    DOMS per workout disappeared by the fourth week of training in experimental but
    not control groups. Aerobic cardioacceleration immediately before each set of
    resistance exercises therefore rapidly eliminates DOMS during vigorous
    progressive resistance training in athletes.
     
  2. Bryan, is there further consequence of this or it is only applicable to the soreness itself. My question is, can we assume that pre-resistance cardioacceleration can also improve hypertrophy or not?

    Its not clear... The relationship between DOMS and growth is co-relational, but not cause-effect.
